The Smooth Alder, also known as Alnus serrulata, is a deciduous tree native to North America. It is commonly found in wetland areas, such as swamps, marshes, and along stream banks.
The Smooth Alder is known for its smooth, grayish bark and its ability to tolerate wet soil conditions. It has dark green, oval-shaped leaves with serrated edges, which turn yellow in the fall before dropping off. The tree produces small, cone-like fruits that contain seeds.
The Smooth Alder is often used in landscaping projects for erosion control, stream bank stabilization, and as a wildlife habitat. It provides food and shelter for various bird species and other wildlife.
